ITED STATES WILLIAM NOVIGK, OF BROOKLYN, NEW YORK.

FRAME FOR FLEXIBLE SCREENS, ETC.

Application filed January 1'7, 1921.

T 0 all whom it may concern Be it known that 1, WILLIAM Noviox, a citize of Russia, having declared my intention of becoming a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Frames for Flexible Screens, Etc, of which the following is a specification.

While applicable to analogous purposes and uses, my improvements are designed more particularly for embodiment in win dow and door frames, etc, in which a screen of netting or other flexible cloth or material is mounted,the object of the invention being primarily to adapt the supporting frame to washable screening material, and distinctive feature of the invention relating to the means whereby such material may be detachably secured in position in such manner as to draw and hold it taut,--other fea tures of the invention relating to minor de tails of construction, as hereinafter de scribed and claimed specifically.

In the accompanying drawings,

Figs. 10 and 11, are isometrical views showing means for rendering the frame adjustable in width horizontally.

Fig. 12, is a transverse section'taken upon plane of line 1212, Fig. 10;

Fig. 13, is a sectional detail taken upon plane of line 1313, Fig. 12;

Serial No. 437,773.

Fig. 1a, is'a transverse section taken upon plane of line 1 1, 14, Fig. 11;

Fig. 15, is a sectional view of the hinged sideof the frame, opened up in part;

F 1g. 16, is a sectional detail showing a modification in the form of tongue and groove by means of which the screen is drawn taut.

My screen frame is duplex in character, being formed of what may be designated as the basic section B, to which the screen cloth S, is directly applied, and of the binder section B. These two sections may be hinged together as indicated in Figs. 7 and 8, although this is not an essential feature of the invention, as the binder section B, may be otherwise and detachably secured to the basic section B, according to circumstances and requirements of special use. In other words, each of the sections B, B, is a complete frame in itself,the coincidental side and cross members of which are adapted to interlock to secure and hold the screen S, between them,-means being provided whereby the two sections may be rigidly secured together for such purpose.

The basic section B, is formed with a circumscribing flange a, on its inner or opening edge, adjoining which is a groove a, on the other side of which latter is a marginal flange aflextending laterally in a plane at right angles to that of the said edge flange (1-.

Conversely, the inner face of the binder section B, is formed with a tongue 73, adapted to extend into the groove a, in the basic ection B, as shown in Figs. 2, 3, 4: and 16, when the said binder section B, is applied and secured to said basic section B. It is to be understood that the flanges a, a groove a, and tongue 6, extend around and on all four sides of the frame section B, B, so as to afford a continuous and complete interlocking of the opposed faces of the said frame sections B, B.

In applying the flexible screen S, to the frame, the edges of the fabric are primarily attached to the marginal flange (f, of the basic section B, by means of spring clips 76, is, thereby holding the sheet S, tentatively in position. The slack of the screen is then taken up, and the sheet drawn taut and even, by the application of the binder section B, of the frame to the basic section B, thereof,

the tongue 6, of the binder section B, push ing the adjacent portion of the screen S, into the groove a, and retaining 1t therein,

. sizes of apertures to be screened.

thereby stretching the body of the screen tight within the frame aperture, and so maintaining it until released by the with drawal of the binder section B. The size of the screen cloth S,is of course so proportioned as related to the size of the basic section as to effect the attainment of this result, the amount of slack provided for when the edges of the screen are attached to the flange by the clips 70, 7e, being only suflicient, when: taken up by the drawing tongue t to; insure tautness of the screen between the side and cross members of said frame.

t is to be noted in this connection that by my construction and arrangement of. interlocking tongues and grooves in the opposed faces of the sections of thefranie, and by my method of applying the screen cloth. thereto, the tension and strain on the latter is uniform on all sides and in all directions, so that a level, even plane of scrcen surface is attained by substantially automatic means.

In Figs. 1, 2 and 7, my screen frame is of fi'Xed dimensions adapted to special require ments, as where furnished for a building in course of construction, or for prescribed lVhen manufactured as a stock article for the trade generally, I prefer to make my. screen frame adjustable in horizontal width, and this I. accomplish by dividing the cross bars ofeach section B, B, centrally, or approximately so, and by uniting the adjoining ends thereof by means of tubular coupling sleeves G, C, clamping'means being also provided whereby the sleeves may be rigidly secured to said abutting medial ends of-the cross bars, as shown more particularly in Figs. 10 to 1:4 inclusive of the drawings.

Thus the clamping means may consist of binding screws (Z, Z, the threaded shanks of p which extend through slots 0*, c, in the coupling sleeves C, C, and engage with fe male screw threads formed for the purpose in the cross members of the frame, or .1n

metallicnut plates 6*, b countersunk therein as shown particularly in Figs. 12, 13,and 14.

The coupling sleeves are preferably made of sheet metal, and in conformity with the cross section of the frame sections to which they are applied, as shown particularly in Figs. 12 and 14. That is to say, the coupling sleeves C, C, being continuously tubular for their full length, embrace the interlocking flanges, tongue and groove of both the basic section B, and the binder. section B, and. interlock with each other in like manner.

This continuous tubular structure of the coupling sleeves C, C, is illustrated clearly in Figs. 12 and 14, which, aside from, the slots 0", 0", would represent the cross section of the said sleeves at any portion of their length, so that they constitute, practically, continuations of the tongues and grooves of the frame sections B, B, the opposed medial ends of which are slidably adjustable within said coupling sleeves, in such manner that the interlocking tubular tongues and grooves of the coupling sections C, C, are adapted to hold the screen cloth S, taut, as do the tongues and grooves of the frame sections B, B, which they straddle.

Y, Y, Figs. 1 and 9, are corner yokes which may be applied to the unhinged sides of the frame sections to retain them in operative engagement, .turnable hooks h, it, being provided to detachably secure said yokes in position as shown particularly in Fig. 9.

The dia onal stri s Y Y shown in Fi s.

1 and 8, are used to afford a balanced symmetrical eflect of the frame as a unitary structure. i

It is obvious that the grooves 64, and tongues t, for taking up the slack of the screen S, may be varied in form in cross section without departing-from the spirit and intent of my invention,the essential feature in this respect being a recess (groove (0) for the reception of the slack, and a coincidental protuberance (tongue t) adaptedv to position and hold such: slack in said recess. For instance, in most of the figures of the drawings relating thereto the groove or recess a, and the tenon or. tongue t, are shown as of rectangular form in cross section,'while in Figs. 4: and 1 6, modificationsare shown which answer the same purpose.

In Figs. 1 and 2, the use of turn buttons 6, e, is shown for the purpose of holding my screen frame in position in awindow or door casing or the like, although any old and well known mechanical expedientmay be resorted to for this purpose.

From the foregoing description it will be readily understood that my improved automatic tension frame is adapted to the useof screens of flexible, but also of washable, material, it being a simple matter to remove and replace thescreen as desired.

Furthermore my invention is not only adaptable for use in connection with window and door screens but also for embodiment in embroidery frames, or, as a container for tapestry and other decorative panels, etc., where demountable means of support is a desideratum.

When applied to buildings in course of construction the basic section B, of my dupleX screen frame may be permanently incorporated with the window or door casings, the binder sections to be added thereto sub sequently.

What I claim as my invention and desire to secure by Letters Patent is, n

1. In a duplex frame of-the character designated, the combination of a basic section formed with an inner circumscribing flange, a groove, and a marginal flange extending laterally in a plane at right angles to the said groove and circumscribing flange and adapted to hold the bight of the edge of the flexible screen, a binding section formed With a tongue fitting in said groove in the basic section, said flexible screen, means cooperating With said circumscribing flange to hold the screen taut on said basic section and means for detachably securing the basic section and the binding section together, for the purpose described.

2. In a duplex frame of the character designated, the combination of a basic section formed with an inner circumscribing flange, a groove, and a marginal flange extending laterally in a plane at right angles to the said groove and circumscribing flange and adapted to hold the bight of the edge of the flexible screen, a binding section formed With a tongue fitting in said groove in the basic section, said flexible screen, and means for detachably securing the basic sectionand the binding section together, together With spring clips for tentatively securing the bights of the edges of the screen to the said marginal flanges on the base section, for the purpose described.

3. A duplex frame of the character designated, comprising a basic section and a binder section, the two sections being formed With interlocking tongues and grooves and With flanges for engagement with the edges of a flexible screen, and said flexible screen, means for detachably securing the said sections together, and means for adjusting the horizontal Width of said sections, consisting of slotted metallic coupling sleeves fitting over the opposed ends of the frame sections, and binding screws extending through the slots in the said coupling sleeves and engaging with said opposed ends of the frame sections, for the purpose described.
